    A starting aid for an internal combustion engine comprises a tubular extension in the end of which is wound an electric heating element. Surrounding the extension is a tubular member which ever at least a substantial portion of its length is mounted on spaced relationship to the extension. The member is formed from heat resistant material and acts to minimize the temperature attained by the extension when the aid is in use.

    However, the reliability of such a device is not high enough. A tubular 2 θth body element located inside the combustion chamber is exposed to hot combustion products. Fuel has high thermal and mechanical loads, J5, which leads to its destruction.
    Pel invention - improving the reliability of the device.
    The goal is achieved by the fact that around the tubular element there is an end screen made of high-temperature alloy, and most of the inner surface of the annular screen is located with a-gap relative to the tubular element.
    The end of the screen adjacent to the housing may be provided with a flange.
    The length of the screen may be equal to the length of the tubular element of the housing.
    The wall of the screen near the housing may have a hole.
    The outer surface of the tubular housing element may be provided with an annular groove and the end portion of the screen is placed in this groove.
    The end of the screen remote from the housing may be in the form of a cap and have openings.
    The end of the screen removed from the case. It can also be made of a reduced diameter, tightly covering the outer surface of the tubular element of the housing and having two openings located along its longitudinal axis.
    In FIG. 1 shows a cylinder head of an engine with an installed device, a section; in FIG. 2 - the first embodiment of the device; in FIG. 3 - the second embodiment of the device; in FIG. 4 - the third embodiment of the device; in FIG. 5 is a fourth embodiment of the device.
    The starting auxiliary device comprises a housing 1 with a thread 2, which is mounted in the threaded hole of the cylinder head 3 of the engine. The outer end 4 of the housing 1 is in the form of a hexagon to facilitate its mounting on the engine. The housing 1 has at one end a tubular element 5 partially located in the combustion chamber 6. An electric heating element 7 is placed at the open end of the tubular element 5, forming a heated surface inside the combustion chamber 6. An annular screen 8 made of a high-temperature alloy is installed around the tubular element 5. A large part of the inner surface 9 of the screen 8 is located with a gap relative to the tubular element 5. The annular screen 8 at the end adjacent to the housing 1 has a flange 10. The length of the annular screen 8 is equal to the length of the tubular element 5 of the housing 1 (in the device variants shown on 'Fig. 1 and 2). 1
    The wall of the annular screen 8 may be provided with one or more holes 11 located close to the housing 1. The holes create a gas flow through the annular gap between the annular screen 8 and the tubular element 5.
    In the embodiment shown in FIG. 3, the outer surface 12 of the tubular element 5 is provided with an annular groove 13 in which the end portion 14 of the screen 8 is placed, for example, by rolling the material of the screen 8.
    In the embodiment shown in FIG. .4, the end of the screen 8 remote from the housing 1 is made in the form of a cap 15, which is equipped with openings .16, allowing the fuel of the air mixture to come into contact with the heated parts of the device. The cap 15 reduces shock loads on the heating element 7.
    In the embodiment shown in FIG. 5, the end of the screen 8, which is remote from the housing 1, is made of reduced diameter and tightly covers the outer surface 12 of the tubular element 5. Two holes 17 located along its axis allow gas to flow in the gap between the tubular element 5 and the screen 8.
    The device operates as follows,.
    During engine starting, voltage is applied to the output of the glow element. The electric current flowing through the heating element 7 heats it to operating temperature and contributes to the initial ignition of the fuel.
    The starting aid provided with an annular screen has greater reliability by lowering the temperature of the tubular element, and hence the heating element. In addition, the screen provides some protection for parts of the device from vibrations that occur during engine operation.

    The invention relates to engine testing, in particular to devices for facilitating the start of internal combustion engines. A starting auxiliary device for an internal combustion engine is known, comprising a housing adapted to be mounted in the cylinder head bore of the engine and having a tubular element at one end partially disposed in the engine combustion measure and a coiled electric heating element located at the open end. tubular element to form a heated surface in the combustion chamber 1. However, the reliability of such a device is not high enough. The tubular element of the housing, located inside the combustion chamber, is subjected to the effects of hot combustion products. The fuel has high thermal and mechanical loads, which leads to its destruction. The purpose of the invention is to increase the reliability of the device. The goal is achieved by installing an end shield around the tubular element made of a high-temperature alloy, with a large part of the inner surface of the annular shield located with a gap relative to the tubular element. The end of the shield adjacent to the housing may be provided with a flange. The length of the screen may be equal to the length of the tubular body element. The screen wall near the case may have a hole. The outer surface of the tubular body element may be provided with an annular groove and the end portion of the screen is placed in this groove. Remote from the body end of the screen can be made in the form of a cap and have holes. Remote from the body end of the screen. It can also be made of a reduced diameter, tightly cover the outer surface of the tubes of the housing element and have two holes along its longitudinal axis. FIG. 1. Gives the cylinder head of the engine with the installed device, cut; in fig. 2 - the first embodiment of the device; Fig 3 is a second embodiment of the device; in fig. 4 shows a third embodiment of the device; in fig. 5 - the fourth version of the device. The starting auxiliary device comprises a housing 1 with a thread 2, which is mounted in the threaded bore of the head 3 of the engine cylinder. The outer end 4 of the housing 1 has the shape of a hexagon to facilitate its mounting on the engine. The housing 1 has a tubular element 5 at one end, partially located in the combustion chamber 6. At the open end of the tubular element 5 an electrical heating element 7 is placed, forming a heated surface inside the combustion chamber b. Around the tubular element 5 is installed a CS, an end shield 8 made of a high-temperature alloy. Most of the inner surface 9 of the screen 8 is located with a gap relative to the tubular element 5. The annular shield 8 at the end adjacent to the housing 1 has a flange 10. The length of the annular screen 8 is equal to d, the pin of the tubular element 5 of the housing 1 (in the variants of the device shown in figs 1 and 2). The ring screen 8 may be provided with one or several holes 11 located not far from the housing 1. The hole creates a flow of gases through the ring hole between the ring screen 8 and the tubular element 5. In the embodiment shown in FIG. 3 The outer surface 12 of the tubular element 5 is provided with an annular groove 13 in which the end part 14 of the screen 8 is placed, for example, by rolling the material of the screen 8. In the embodiment shown in FIG. 4, the end of the screen 8 removed from the housing 1 is designed in the form of a cap 15, which is provided with openings 16 allowing the air mixture fuel to come into contact with the heated parts of the device. The cap 15 reduces the shock load on the heating element 7. In the embodiment shown in FIG. 5, the shield 8’s distance from the body 1 is made of a reduced diameter and tightly encloses the outer surface 12 of the tubular element 5. Along its axis, two openings 17 provide gas flow in the gap between the tubular element 5 and the screen 8. The device operates as follows:. In the process of starting the engine, a voltage is applied to the output of the incandescent element. The electric current flowing through the heating element 7 heats it to the operating temperature and contributes to the initial ignition of the fuel. The starting aid, provided with an annular shield, is more reliable by lowering the temperature of the tubular member, and therefore the heating element. In addition, the screen provides some protection for parts of the device from vibrations that occur during engine operation. 1.
